With a little more than a week of training camp in the books, here's a breakdown of the hottest offensive position battles:

Jets quarterback: Geno Smith vs. Mark Sanchez

It's not clear whether the green Smith has passed the veteran Sanchez in the competition. But based on the reports ranging from "dead heat" to a "slight lead" for the rookie, it is clear that Smith has made up plenty of ground in a short time.

Coach Rex Ryan dismissed concerns about Smith's conditioning, and offensive coordinator Marty Mornhinweg has been impressed by Smith's expedited progress in learning the Jets' West Coast-tinged scheme. Also in Smith's favor: Ryan is intrigued by what he can add with read-option wrinkles. The man who drafted Smith in the second round, first-year GM John Idzik, also plans to play a part in picking the starting QB.

Forecast: Before camp, Sanchez seemed to have a tenuous lead based mainly on his experience. But if Smith can support his accelerated practice reps with solid preseason play, he can pull a mild upset.

Eagles quarterback: Michael Vick vs. Nick Foles

Coach Chip Kelly began training camp as noncommittal as he's been through the entire offseason in determining which quarterback is best to handle his first NFL offense. Through minicamp, it appeared Foles had pulled ahead a bit with his strong arm, and his bevy of first-team reps were enough to frustrate Vick. With practice heating up the past week, however, the savvier Vick has been coming on and Foles hasn't stood out.

Although rookie Matt Barkley may be Kelly's ideal choice in time, he's not quite ready and appears to be headed for a developmental 2013.

Forecast: Live action will be huge in this battle, as Kelly will want to see Vick and Foles operate his offense against defenses in a variety of situations. Given that Foles hasn't taken advantage of his previously solid position, it's tilting back to Vick keeping the job.

Broncos running back: Ronnie Hillman vs. Montee Ball

The Broncos opened up the job after releasing Willis McGahee, and Hillman so far has performed the best. He’s shown significant improvement from his rookie season with his all-around game, and in particular has impressed with one element that was missing from Denver’s rushing attack last season—the ability to reel off big runs. The rookie Ball has seen his share of first-team reps, and his compact power frame, red zone finishing skills and pass-catching ability make him worthy of receiving a good chunk of the carries.

Forecast: Though it will be interesting to see how the workload is split in preseason games, this sets up as a straight-up committee—especially when you consider John Fox’s history with the Panthers. Think of Hillman in the DeAngelo Williams role, and Ball doing a lot to remind Fox of Jonathan Stewart.

Giants running back: David Wilson vs. Andre Brown

When the Giants issued their first depth chart in camp this past week, Wilson and Brown were listed as co-No. 1s in the race to replace Ahmad Bradshaw. Brown is the option Tom Coughlin can rely to secure the ball, pound between the tackles and deliver in short-yardage and red-zone situations with his no-nonsense style.

But even if the Giants aren’t sold on Wilson as a big-load back, he has the speed and big-play flair that will warrant significant touches as a change-of-pace back. Limiting Wilson’s offensive work will also allow them to keep his legs fresh for the return game.

Forecast: Expect them to become some sort of hybrid of past New York backfields “Thunder and Lightning” and “Earth, Wind and Fire.” The Giants’ new duo may not have a colorful, elemental nickname yet, but they can be effective together.

Pittsburgh is putting a lot of emphasis in improving its power running game during training camp, and Bell looks the part of a steady runner on early downs, with the hands and pass protection ability to also stay on the field on third down.

Forecast: There’s no reason to put Redman or Dwyer in a committee with Bell. He carried a heavy load at Michigan State and is ready to handle 20-25 attempts per game for the Steelers. There’s no question he is their man.

Bills quarterback: EJ Manuel vs. Kevin Kolb

Buffalo general manager Doug Whaley has shared his giddiness about Manuel’s future, saying the first-round rookie has the “it factor” and will be “the face of the franchise.” There’s much to like about Manuel’s strong arm and athleticism to deliver on that promise, but in the short term, he’s still a raw passing prospect. The Bills don’t want to rush him and put him in position to fail when he’s not quite ready to succeed.

Forecast: Coach Doug Marrone plans to take an equally long look at both Manuel and Kolb, who suffered a minor knee injury Saturday, in game action. Much to his chagrin, Kolb feels like a veteran place-holder who’s there to buy time until the Bills are confident enough to play Manuel sometime this season.

Dolphins running back: Lamar Miller vs. Daniel Thomas

There are big expectations for Miller in Miami’s backfield, and he hasn’t let the team down so far. He’s the Dolphins' clear No. 1, as he’s done everything well. Thomas, who has battled some ball security issues, has faded into the background.

Forecast: Miller will be the bell cow to replace Reggie Bush and should be very productive in that role.
